Designed With Quality In Mind

With over 120 years of combined experience, our GC scientists have the technological know-how to produce quality GC columns! Many spent years creating keystone GC phases at J&W Scientific prior to joining our team. Our foundation in expertise means you get products designed to work out-of-the-box, headache free.

Aggressive indivual QC testing for every Zebron column

Excellent sensitivity and reproducibility

Long GC column lifetimes

Low bleed GC column performance

Our Innovation, Your Success

In 1997, Phenomenex acquired GC manufacturing capabilities from Dr. Robert Wohleb, the "W" of J&W Scientific. We set out to pioneer the development of a new family of GC columns, and in 1999 the original Zebron columns came to life! The Zebron column family continues to evolve to help overcome obstacles you face every day - our innovation comes from solving real-world GC problems.

What Customers Are Saying

"The Zebron ZB-5 column has proven to be a winner. It produces high resolution chromatography in a very reliable manner. Guaranteed quality at an affordable price, you can't go wrong."

Carl Adix, BASF Corporation

"I analyze phenolics by GC/MS. After each run with [Agilent] J&W's DB-5 I had to clean the injector and replace the gold seal and inlet line and trim 4 to 5 feet of column. After most runs with Zebron, I could get away with just changing the inlet and not having to clean or trim the column. The separation was the same, but the Zebron lasted about 4 to 5 times longer, which for means means saving at least $5,000 a year."

Sam Sabella, BASF

"I was very glad to receive all six ZB-WAX columns overnight. It was nice to know that even if we order columns at 5:00 pm (Eastern Time), you can deliver them overnight! How simple to order!"

Analytical Chemist, Industrial Chemical Company

"The chromatography quality and performance are excellent. Column bleed is minimal at 320 °C. Peak quality remains good for 5 to 6 months averaging 40 injections in a 24 hour period, 6 to 7 days per week."
